[0002] Electrode plates are key components of electrochemical devices such as batteries, and they play an important role and have a significant impact on the performance of electrochemical devices such as batteries. In some batteries, meat-biased plates are required. The so-called meat-biased plates refer to plates with uneven thickness in design, for example, plates with thicker heads and thinner tails. For meat-biased plates, due to the uneven thickness of the plates, the shapes of the plates are asymmetric. Therefore, in the plate winding process, the meat-biased plates need to be supplied to the winding station of the plate winding machine in the correct orientation, for example, with the thicker head at the front and the thinner tail at the back. At present, manual operation and detection are mainly relied on to ensure the correct orientation of the meat-biased plates. Therefore, there is a problem of the plates facing the wrong direction due to human negligence and mistakes. Utility Model Content

[0025] As attached Figure 1 As shown, the device for detecting the orientation of a meat-biased electrode plate of this embodiment includes an electrode plate conveying unit 1 , a thickness detecting unit 2 and an electrode plate accelerating unit 3 .
[0026] The electrode plate conveying part 1 includes a chain 11, a push block 12 and a guide rail 13. The push block 12 is arranged on the chain 11. When the chain 11 moves along the conveying direction, the push block 12 is driven to move together, and the push block 12 pushes the meat-biased electrode plate 4 to move on the guide rail 13.
[0027] The thickness detection unit 2 includes a pressure roller 21, a lever mechanism 22, a distance sensor 23 and a reset spring 24. The lever mechanism 22 is composed of an L-shaped rod, which serves to amplify the stroke of the pressure roller 21. The short handle of the L-shaped rod is parallel to the guide rail, and the long handle is perpendicular to the guide rail. The L-shaped rod can rotate with the end of the short handle as a fulcrum. The pressure roller 21 is arranged above the guide rail 13 and connected to the lever mechanism 22. Specifically, the pressure roller 21 is connected near the connection between the short handle and the long handle of the L-shaped rod. The height of the pressure roller 21 from the guide rail 13 is less than the minimum thickness of the meat-biased plate 4. Therefore, when the meat-biased plate 4 passes from the bottom of the pressure roller 21, the pressure roller 21 applies downward pressure to the head-biased plate 4, and the pressure roller 21 is lifted due to the upward reaction force. The L-shaped rod rotates with the fulcrum 221 as the rotation center, and the end of the long handle of the L-shaped rod is separated from the distance sensor 23. Since the thickness of the head and tail of the meat-biased plate 4 is different, when the head and tail pass through, the pressure roller 21 is lifted to different heights, resulting in different strokes of the end of the long handle of the L-shaped rod, so that the head and tail of the meat-biased plate 4 can be distinguished according to the distance between the end of the long handle of the L-shaped rod and the distance sensor 23, thereby achieving the purpose of detecting whether the orientation of the meat-biased plate 4 is correct. When the meat-biased plate 4 passes under the pressure roller 21 as a whole, the return spring 24 restores the L-shaped rod and the pressure roller 21 to their original positions.
[0028] like Figure 1 and Figure 2 As shown, the pole plate acceleration unit 3 is arranged below the guide rail 13 at a position opposite to the pressure roller 21. When the meat-biased pole plate 4 is decelerated due to the resistance of the pressure roller 21, the pole plate acceleration unit 3 can apply friction force to the meat-biased pole plate 4 to accelerate the meat-biased pole plate 4. The pole plate acceleration unit 3 includes a gear 31 and a friction wheel 32, and the gear 31 is coaxially connected with the friction wheel 32. The gear 31 is engaged with the chain 11, and rotates driven by the chain 11, thereby driving the friction wheel 32 to rotate. The friction wheel 32 is arranged directly below the pressure roller 21, and the friction wheel 32 is arranged to meet the following conditions: the rotation speed of the friction wheel 32 is greater than the moving speed of the rack, and when the meat-biased pole plate 4 passes between the friction wheel 32 and the pressure roller 21, it can contact the meat-biased pole plate 4. By setting the friction wheel 32 to meet the above conditions, when the meat-biased pole plate 4 passes between the friction wheel 32 and the pressure roller 21, the friction wheel 32 contacts the meat-biased pole plate 4 from below. Since the rotation speed of the friction wheel 32 is greater than the forward speed of the chain 11, the friction wheel 32 applies a forward friction force to the meat-biased pole plate 4, driving the meat-biased pole plate 4 to move forward from the push block 12 and separate from the push block 12.
[0029] Next, refer to Figure 3 The detection process of the meat-biased electrode plate orientation detection device of this embodiment is described.
[0030] like Figure 3As shown, a plurality of meat-biased plates 4 move forward on the guide rail 13 under the push of a plurality of push blocks 12, with the thicker head located in the front and the thinner tail located in the rear. When the head of the meat-biased plate 4 reaches between the pressure roller 21 and the friction wheel 32, the friction wheel 32 contacts the meat-biased plate 4 from below. Since the rotation speed of the friction wheel 32 is greater than the forward speed of the push block 12, the friction wheel 32 applies a forward friction force to the meat-biased plate 4, driving the meat-biased plate 4 to move forward from the push block 12 and separate from the push block 12. In this way, the thinner tail of the meat-biased plate 4 can be prevented from being deformed under the thrust of the push block 12 when the pressure roller 21 applies resistance to the meat-biased plate 4. In addition, since the friction wheel 32 is arranged below the meat-biased plate 4 and is opposite to the pressure roller 21, it can offset the downward pressure of the pressure roller 21 on the meat-biased plate 4, and reduce the degree of deformation of the meat-biased plate 4 due to the pressure of the pressure roller 21.
[0031] When the meat-biased plate 4 contacts the friction wheel 32, since the thickness of the meat-biased plate 4 is greater than the height of the pressure roller 21, the pressure roller 21 is subjected to an upward force, the L-shaped rod rotates with the fulcrum 221 as the rotation center, and the end of the long handle end of the L-shaped rod is separated from the distance sensor 23. At this time, the separation amount of the end of the long handle end of the L-shaped rod is measured by the distance sensor 23, so that the thickness of the meat-biased plate 4 can be measured. Since the thickness of the head and tail of the meat-biased plate 4 is different, the height of the pressure roller 21 is different when the head and tail pass through, resulting in different strokes of the end of the long handle end of the L-shaped rod, so that the head and tail of the meat-biased plate 4 can be distinguished according to the distance between the end of the long handle end of the L-shaped rod and the distance sensor 23, so as to achieve the purpose of detecting whether the orientation of the meat-biased plate 4 is correct. After the meat-biased plate 4 passes between the pressure roller 21 and the friction wheel 32 as a whole, the reset spring 122 restores the L-shaped rod and the pressure roller 21 to their original positions. At this time, since the biased meat plate 4 is no longer subjected to the forward friction force of the friction wheel 32, it slows down and stays on the guide rail 13, and the push block 12 contacts the biased meat plate 4 again and pushes the biased meat plate 4 to continue moving forward.
[0032] An embodiment of the device for detecting the orientation of a meat-biased electrode of the present invention has been described above, but the present invention is not limited to the above embodiment and various changes can be made without departing from the gist of the present invention.
[0033] For example, in the above embodiment, the chain 11 is used as the power source of the plate conveying unit 1, but a belt may be used instead of the chain.
[0034] In addition, in the above embodiment, the gear 31 is engaged with the chain 11 to provide power to the friction wheel 32 , but a separate power source may be provided to drive the friction wheel 32 .
[0035] In addition, in the above embodiments, the friction wheel 32 is arranged below the meat-biased electrode plate 4, but the friction wheel 32 can also be arranged above the meat-biased electrode plate 4, as long as it can apply a boosting force to the meat-biased electrode plate 4.
[0036] It is obvious to those skilled in the art that various omissions, changes and modifications can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, it should be understood that the present invention includes changes and modifications within the scope of the attached claims and their equivalents. In particular, it should be understood that any combination of any part or all of any two or more of the above-mentioned embodiments and their modifications can be understood to be within the scope of the present invention.
